Out of the three bike nerds living in the apartment, we have quite a few fluted cranksets that were all very inexpensive:

There's a SR Apex, which uses a strange 118BCD and is therefore almost worthless.

There's an unbranded Ofmega/Avocet campy ripoff threaded for triple use in 144BCD. This crank is really awesome except for the fact that it uses a non-standard Ofmega BB taper, so it's almost worthless. I was surprised to find this in a dumpster until I learned about the BB taper.

My Raleigh has a Shimano 600 crank that I got new old stock for pretty cheap, 130BCD. It's of the first 600 group that had the great engravings on all the parts, and looks pretty good. It has a lot thicker construction than most other cranks I've seen of this style, and should be really durable. Time will tell.

The other day I won an "Azzurro" crank on ebay, reportedly made by Gipiemme. 144BCD. It has the two separate flutes on the arms just like Gipiemme cranks, only the forging is not so hot and the finish is worse. Luckily the previous owner painstakingly polished it, giving it a decent look, at least from the front. http://cgi.ebay.com/ws/eBayISAPI.dll...MEWN%3AIT&rd=1
Pretty good for $3.25 plus shipping.

If you're just going for the fluted look, you can do it pretty cheaply. Campagnolo cranks are beautiful, but something cheaper will probably work for the majority of riders.
